i have a 2000 ws6 trans am i have a 4l60e in it with a trans go pake and 4.000 stall. it just started jumpong in park to drive or when it shifts in to 2nd i'm geting a code p0748 can anyone tell me what it is and how to fix it,,,,,

 

Like I said last night, bring it up to my work tonight and I'll take a look at it. I'll let you know what the code is reading. Does anyone think this may be a solenoid? When he puts it in gear from reverse, it jerks pretty hard. Now when he drives it after it heats up, the gear (not sure which one or if all) are making a clicking sound I think. I wonder if it might have something to do with a solenoid. He just got the shift kit in about 6 weeks ago. I'll get him on here to give some more descriptive info.

 

sometimes it jerks pretty hard from park to drive or reverse and when i drive it jerks hard when it shifts in to 2nd...... kirby i have had my shift kit longer then that
